Description

Vorrichtung zum Blankglühen. Die Erfindung stellt eine Vorrichtung dar, um bei dünnwandigen, luftdicht abgeschlossenen Gefäßen, die zum Blankglühen mittels Sauerstoff aufnehmender Mittel dienen, einen für das Glühgut unschädlichen Druckausgleich zu schaffen, durch den eine Fox-rnänderung des Deckels und der Gefäßwandungen verhindert wird. -In der Zeichnung steilt a das Glühgefäß, b den mit einer Öffnung versehenen Verschlußderkel, c einen auf diesem zur Aufnahme einer Sanddichtung bestimmten Aufsatz dar.Device for bright annealing. The invention provides an apparatus in the case of thin-walled, airtight vessels, which cause the bright glow serve by means of oxygen-absorbing agents, one that is harmless to the material to be annealed To create pressure equalization by changing the lid and the vessel walls is prevented. -In the drawing, a steepens the incandescent vessel, b the one with an opening provided closure cap, c one intended on this for receiving a sand seal Essay.

In dem Glühgefäß a befindet sich ein Rohr d mit siebartigen Öffnungen e am Umfang, in- das- ein Rohr f hineinragt, welches mit der äußeren Atmosphäre in Verbindung steht. Der zwischen den beiden Rohren d und f befindliche Raum ist mit einer Sauer= stoff aufnehmenden Masse ausgefüllt.In the annealing vessel a there is a tube d with sieve-like openings e on the circumference, into which a tube f protrudes, which communicates with the external atmosphere communicates. The space between the two tubes d and f is filled with an oxygen-absorbing mass.

Der zum Druckausgleich zwischen äußerer Atmosphäre und dem Gefäßinnern durch Rohr f einströmenden atmosphärischen Luft wird heim Durchgang durch die in der Röhre d! befindlichen, -Sauerstoff aufnehmenden Mittel der für das Glühgut schädliche Sauerstoff entzogen.The one to equalize the pressure between the outside atmosphere and the inside of the vessel Atmospheric air flowing in through tube f is passed through the in the tube d! located, oxygen-absorbing agent of the harmful to the annealing material Oxygen deprived.

Die atmosphärische Luft strömt so lange nach, bis zwischen äußerer Atmosphäre und dem Gefäßinnern Gleichgewichtszustand herrscht.The atmospheric air flows in until between outer The atmosphere and the interior of the vessel are in equilibrium.

PATENT-ANSpRUCH: Vorrichtung zum Blankglühen, wobei zur Erzielung eines Druckausgleichs das Innere des Glühtopfs mit der Außenluft durch eine Röhre verbunden ist und die eintretende atmosphärische Luft über Sauerstoff aufnehmende Mittel geleitet wird, dadurch gekennzeichnet, daß die Sauerstoff aufnehmenden Mittel in einer Röhre (d) untergebracht sind, die durch Öffnungen (e) mit dem Innern des Glühgefäßes und durch die Röhre (f) mit der Außenluft in Verbindung steht. PATENT CLAIM: Apparatus for bright annealing, wherein the interior of the annealing pot is connected to the outside air by a tube to achieve pressure equalization and the atmospheric air entering is passed through oxygen-absorbing means, characterized in that the oxygen-absorbing means are in a tube (d ), which is in communication with the interior of the annealing vessel through openings (e) and with the outside air through the tube (f).
